22.
Which type of front forms when a colder air mass moves toward a warmer air mass. The colder air, which is denser pushes under the warmer air mass. The warmer air rises, cools and condenses forming clouds. Often showers or thunderstorms form. The temperature can change +10ºC once the front has passed through. Winds become gusty and change direction sometimes giving rise to severe thunderstorms.

cold front
b)
warm front
c)
stationary front
d)
occluded front

stationary front
